Before & After: Why the Clear Glaze Matters

KIWI Underglaze without clear glaze compared to the same piece finished with Zinc Free Clear glaze

Left: KIWI Underglaze without a clear glaze — matte and unsealed.
Right: the same piece finished with our Zinc Free Clear glaze — glossy, sealed and food-safe.

🔥 Unofficial tip: KIWI in raku firing

KIWI underglazes have also been used successfully in raku firing under a clear raku glaze – one of our customers has achieved great results with a red underglaze. This is not an official manufacturer recommendation, so always make a test piece first.
